change. In all cases, the side assist will give
a warning for the vehicles it has detected at the
latest when they enter the "blind spot".
© Other vehicles being overtaken
When you are overtaking another vehicle slowly,
with a speed differential of less than 15 km/h,
the warning lamp in the exterior mirror will light
up as soon as the other vehicle enters your blind
spot.
If you are overtaking another vehicle quickly, with
a speed differential of more than 15 km/h, the
warning lamp will not light up.
System limitations
The radar sensors are designed for normal lane
widths and monitor the lanes immediately to the
left and right of your vehicle. In certain situations
the warning lamp on one of the exterior mirrors
may light up even if no vehicle is travelling in an
area that could be critical in the event of a lane
change. For example:
- When you are travelling in a narrow lane or
when you are not travelling in the centre of the
lane. In this case the system may monitor an­
other lane and register a vehicle that is not in
fact travelling in an adjacent lane.
- When you are driving into a bend. The side as­
sist may react to a vehicle two lanes away.
- If the system detects other objects (such as
crash barriers, etc).
- In poor weather conditions. The functionality of
the side assist is then restricted.
The radar sensors ¢ Fig. 98 must not be obstruc­
ted by stickers, bicycle racks, deposits or any oth­
er substances which could impair the function of
the system. For notes on cleaning, please refer to
¢page 236.
.&_ WARNING
-Always watch the road and the area sur­
rounding the vehicle. The side assist feature
is not a substitute for the full concentration
of the driver. The driver is always responsi­
ble for the safety of lane changes and other
manoeuvres. Driver
assist systems
- In certain situations, the system may not
function properly, or the functionality of the
system may be restricted. For example:
- If other vehicles are approaching very
qui ckly, or if you are overtaking other
vehicles quickly. The warning lamp may
not light up in time.
- In poor weather conditions, such as heavy
rain, snow or road spray.
- If you are travelling in very wide lanes, in
tight bends or over crests. The system may
not detect vehicles in the adjacent lane
because they are outside the area covered
by the sensors.
CD CAUTION
Impacts or damage to the bumper, wheel
arches or underbody can cause misalignment
of the sensors. This can impair the functional­
ity of the system. Have the systems checked
by a qualified workshop.
� Note
The warning lamps on the exterior mirrors
may not be properly visible if tinted foil is af­
fixed to the side windows on the driver's or
passenger's side.

aids
General notes
Applies to vehicles: with rear parking aid/parking system
plus/park assist
Various systems are available to help you when
parking or manoeuvring in tight spaces, depend­
ing on the equipment fitted on your vehicle.
The rear parking aid gives an acoustic warning if
there are any obstacles behind the car
¢page 93.
When you are parking, the parking system plus
warns you acoustically and optically about obsta­
cles detected in front of and behind the vehicle
¢ page 94. On vehicles with park assist, the
area detected at the side of the vehicle ®
¢page 94, Fig. 101 is also monitored.
The park assist helps you to find suitable parking
spaces, to manoeuvre the vehicle into spaces par­
allel or perpendicular to the roadside and to drive
out of spaces parallel to the kerb ¢ page 95.
.&_ WARNING
- Always watch the road and the area sur­
rounding the vehicle. The electronic systems
cannot replace the full concentration of the
driver. The driver is always responsible for
safety during parking and all other manoeu­
vres.
- Please note that certain surfaces, such as
clothing fabrics, cannot be detected or dis­
played by the system -risk of accident!
- Sensors have blind spots in which neither
people nor objects are registered. It is par­
ticularly important to ensure that there are
no small children or animals near the vehi­
cle -risk of accident!
- Always keep a close watch on the area
around the vehicle and make full use of the
rear-view mirrors.
CD CAUTION
- The system may not always be able to de­
tect objects such as the following:
- Chains, trailer draw bars, posts or fences Parking
aids
- Objects above the sensors, such as wall
protrusions, etc.
- Objects with certain surfaces or struc­
tures, such as wire fences or powder snow
- As your car moves closer to low obstacles,
they may disappear from the sensors' field
of vision. Please note that you will no longer
be warned about these obstacles.
- Impacts or damage to the radiator grille,
bumper, wheel arches or underbody can
cause misalignment of the sensors. This can
impair the effectiveness of the parking aids.
Have the systems checked by a qualified
workshop.
{D) Note
- In certain situations, a warning may be giv­
en by the system even if there is no obstacle
within range of the sensors. This can be
caused by the following, for instance:
- Certain road surfaces or long grass
- External ultrasound sources, e.g. from
street cleaning vehicles
- Heavy rain or snow or dense exhaust
fumes
- To familiarise yourself with the system, we
recommend that you practise parking in a
quiet location or a car park. The weather
and light conditions should be good.
- You can adjust the volume of the beeps.
- To ensure that the acoustic parking aid
works properly, the sensors must be kept
clean and free of snow and ice.
- There is a slight delay in the picture display.

out of spaces parallel to the kerb. The parking
space can be located between two vehicles or be­
hind one vehicle. The park assist takes over the
steering while the driver is parking the vehicle in
the usual way.
The parking system plus is an integral compo­
nent of the park assist ¢ page 94 and helps you
during the parking manoeuvre.
The park assist sensors are located on the sides
of the front and rear bumpers. Please ensure that
the sensors are kept free of stickers, deposits and
any other substances which could impair the
function of the system. Notes on cleaning
¢page 236.
In short parking spaces, the parking aid warning
tone will sound continuously when the vehicle is
less than approx. 0.20 m away from the obstacle.
Stop moving immediately!
A WARNING
- Please observe the safety warnings ¢ & in
General notes on page 93.
- Please note that the park assist only han­
dles the steering. As the driver you are al­
ways responsible for braking and accelerat­
ing.
- It is the driver's responsibility to decide
whether a parking space shown in the dis­
play is suitable for the vehicle.
- The front of the vehicle swings out during
the parking manoeuvre. Please take all nec­
essary measures to ensure that other road
users are not endangered.
- The steering wheel turns rapidly on its own
when parking the vehicle and leaving the
space. Injury may result if a person reaches
between the spokes on the steering wheel
when it is turning.
CD CAUTION
- Please observe the safety warnings ¢0 in
General notes on page 93.
- In certain situations, the park assist will
guide the vehicle onto or across the kerb,
for instance if other vehicles are parked on
the kerb. You should always be ready to take
96 over
the steering wheel in order to prevent
damage to the tyres and/or wheel rims.
- Certain conditions in and around the park­
ing space can cause unexpected results
when parking.
- Objects such as pillars, posts, etc.
Road surfaces such as loose gravel, snow,
ice, etc.
CD CAUTION
- The sensors may not always be able to de­
tect objects such as trailer draw bars, thin
rails, fences, posts, waste bins and trees,
etc. This could result in damage to your car.
- Please note that the system may not always
be able to detect the surface of certain ob­
jects or substances, such as wire fences or
powder snow, etc. You should therefore
check that the parking space is really large
enough before parking the vehicle.
- Please note that low obstacles detected by
the system may no longer be registered by
the sensors as the car moves closer, so the
system will not give any further warning.
Failure to respond to a parking system
warning can result in damage to your vehi­
cle and other property. Please bear this in
mind, for example, when using the park as­
sist to park behind a truck. Always keep a
close watch on the area in front of and be­
hind the vehicle while parking, and inter­
vene promptly if necessary.
- To prevent damage to the sensors when
washing the vehicle with a high-pressure
cleaner or a steam cleaner, do not hold the
cleaner less than 10 cm away from the sen­
sors and do not keep the cleaner pointed di­
rectly at the sensors.
({D Note
- The electronic stabilisation control (ES()
must not be switched off during the parking
manoeuvre ¢page 104.
- The park assist cannot be used to park the
vehicle on tight bends.

aids
- The best parking results will be achieved if
you position the vehicle as parallel as possi­
ble to the line of parked cars or the kerb be­
fore you start the actual parking manoeu­
vre.
- If there are suitable parking spaces on both
sides of the road (for instance on a one-way
street), you can change the direction of the
turn signals to park on the other side, even
if you have already activated the park assist.

A WARNING
Have the system malfunction repaired by a

«]} Note
You can drive on if the warning/indicator lamp
• or mJ lights up only briefly.
Brakes
New brake pads
New brake pads do not give full braking effect for
the first 400 km, they must first be "bedded in".
However, you can compensate for the slightly re­
duced braking effect by applying more pressure
on the brake pedal. Avoid placing a heavy load on
the brakes during the running-in period.
Wear The rate of wear on the brake pads depends a
great deal on how you drive and the conditions in
which the vehicle is operated. Negative factors
are, for instance, city traffic, frequent short trips
or hard driving with abrupt starts and stops.
Noises Brake noise may develop in certain situations, de­
pending on the speed, braking force and ambient
conditions (such as temperature and relative hu­
midity).
Effect of moisture and salt
In certain conditions, such as in heavy rain, or af­
ter washing the car or driving through water, the
full braking effect can be delayed by moisture (or
in winter by ice) on the discs and brake pads. The
brakes should be "dried" by pressing the pedal to
restore full braking effect.
When you are driving at higher speeds with the
windscreen wipers on, the brake pads are very
briefly brought into contact with the brake discs.
This automatic process which goes unnoticed by
the driver is carried out at regular intervals and is
intended to improve braking response in wet con-
ditions. ..,..
